McAuliffe Family from White Church, County Cork, Ireland to Lykens and Steelton, PA USA

I am attempting to trace my mother's side of the Irish Family Tree back to Ireland. My 3rd great grandmother Margaret Anne McAuliffe (from White Church, County Cork, Ireland) born on or about August 1934. Her parents were Dennis McAuliffe from County Cork, Ireland(b. abbt. 1814 - sometime after 1880 in Lykens, PA) and Ellen (maiden name unknown) from Glanmire, County Cork, Ireland (b. appt. 1805-1870 in Lykens, PA. There were two brothers Michael McAuliffe Sr. (1838-1917) and James McAuliffe (1842-1870). I believe that the siblings moved to Steelton or Harrisburg, PA.

She married Daniel Holleran (born on or about 1835 in County Cork, Ireland) and had 6 children born in Lykens, PA, David D. Holleran (b. abbt. 1858-1945), Daniel Holleran(b. abbt. 1858-1878), Ellen E. Holleran (b. abbt. 1860-1950), Dennis J. Holleran (b. abbt. 1864-1926), John J. Holleran (priest)(b. abbt. 1866-1912), and Mary Holleran (b. abbt. 1872-1878). Most of the family moved from Lykens, PA to Steelton, PA except for Father John J. Holleran who was in Lancaster and York, PA. Daniel Holleran died in 1890 in the town of Lykens, PA USA and is buried in the Irish Catholic Cemetery in Lykens.

I would appreciate any information on Margaret Anne McAuliffe and family.
